Effect of Fiber-Matrix Bond Strength on the Crack Resistance of Synthetic Fiber Reinforced Cementitious Composites

Abstract

Fiber matrix bond characteristics can be changed by treatments of the fiber surface. The effect of such treatments on the fiber reinforced concrete (FRC) tension-softening behavior and crack resistance is studied in this paper. Various R-curve behaviors are predicted based on a simple double cantilevered beam (DCB) model using the experimentally derived tension-softening curves. The result suggests that fiber surface treatments can substantially alter the composite fracture resistance as measured by the R-curve.
